Flowering of the Blue Diamond double late tulip also has the advantage of starting very early in the season, from April, and continuing for a long time, until May.

Using the Blue Diamond Tulip

Colour, vibrancy and opulence… the Blue Diamond Double Late Tulip is perfect for sunny to semi-shaded gardens, planted with other spring-flowering plants, or even other Tulipa varieties , such as Pink Angelica and Violet Victoria’s Secret. . This double late is thus used to bring notes of color in flower beds , flowerbeds , or even rockeries.

On the other hand, this variety is not the most suitable tulip for growing in pots or planters, due to its high stem. If you hope to compose a pretty planter for your balcony, it is better to opt for a variety of tulip with a shorter stem.

The Blue Diamond Tulip also makes a very attractive cut flower . So plan to plant a few extra bulbs for the cut. Indeed, the flower lasts a long time in a vase, and brings a bohemian chic note to an interior decoration.

Growing the Blue Diamond Tulip

Location

The Blue Diamond tulip is grown in a well-drained and cool soil, rich and light, loose and deep, preferably in a sunny location for better flowering. Otherwise, it will support a semi-shaded exposure.

Planting

Plant your Blue Diamond tulips in the fall, from September to December , after deeply loosening the soil . It is therefore better to plant before the first frosts, which would make the task considerably more difficult.

Don’t be afraid to expose your Blue Diamond tulip bulbs to the harsh winter weather. These plants just need to be subjected to a period of cold to flower the following spring. Thus, in open ground, the bulb is able to withstand all weather conditions, and it survives down to -15°C.

Once the soil has been prepared, install your bulbs 15 cm deep , points upwards, and space them about ten centimeters apart.

Maintenance

Blue Diamond tulip bulbs should only be watered during prolonged dry spells. Fertilizer can be added in early spring to encourage flowering.

Although hardy, this variety is not a perennial tulip. Indeed, its flowers are beautiful only in the very first year. It is therefore preferable to cultivate it as an annual and to pull out the bulbs once the season is over, to plant new ones the following fall. Once the flowers have faded, cut the flower stalks and let the leaves dry completely before cutting them (they must be completely yellow). Only then can you pull out the bulbs.
